Looking at the thread "How Much is too Much?" got me wondering: When refilling the crankcase after an oil/filter change, are you the type who: A) Refills with whatever amount the owner's manual calls for (i.e., 4.5qts, 5qts), regardless of the dipstick reading. "It says add 5 quarts, so I'm adding 5 quarts!" OR B) Refills with the amount of oil necessary to get the level on the dipstick in the proper range. This may mean using anywhere from 1/2 - 1 quart of fresh oil less than what is called for. Just wondering. Even though I try to let the oil drain out as long as possible, refilling with the specified amount always leads to an overfill situation on the dipstick. I know you can never get every last drop of old oil out. Also, it's important to keep checking the level periodically.
